         3 . The autonomous driving device according to  claim 1 , wherein
 the traveling control unit is configured to cause the vehicle to travel in manned mode and   the notification unit is configured to send the notification to the outside to indicate that the occupant has not gotten out of the vehicle when the getting in-out detection unit does not detect that the occupant has gotten out of the vehicle within the predetermined getting in-out determination time after the vehicle has arrived at the destination.   
     
     
         4 . The autonomous driving device according to  claim 1 , wherein
 the notification is sent to a reception device external to the vehicle.   
     
     
         5 . The autonomous driving device according  claim 1 , wherein
 the notification is output using a sound, a light, or a display.   
     
     
         6 . The autonomous driving device according to  claim 1 , further comprising
 a travel plan generation unit configured to determine a route to the destination wherein   the traveling control unit is configured to cause the vehicle to autonomously travel along the route.   
     
     
         7 . The autonomous driving device according to  claim 1 , further comprising
 a destination acceptance unit configured to accept a setting of the destination.   
     
     
         8 . The autonomous driving device according to  claim 1 , wherein
 the getting in-out detection unit is configured to detect whether the occupant has gotten in or gotten out of the vehicle based on a detection result of a sensor or an image of an interior of the vehicle captured by a camera.   
     
     
         9 . The autonomous driving device according to  claim 8 , wherein
 the sensor includes at least one of a door open-close sensor, a load sensor, a seating sensor, or an infrared ray sensor,   the door open-close sensor is configured to detect whether a door is open or closed,   the load sensor is configured to detect a weight of the vehicle,   the seating sensor is configured to detect a pressure applied to a seat.   
     
     
         10 . The autonomous driving device according to  claim 1 , wherein
 the arrival determination unit is configured to determine whether the vehicle has arrived at the destination based on vehicle position information including a position of the vehicle on a map at a time when the arrival determination unit determines whether the vehicle has arrived at the destination.   
     
     
         11 . The autonomous driving device according to  claim 10 , wherein
 the position of the vehicle on the map is recognized based on map information stored in a map database and Global Positioning System information entered externally.   
     
     
         12 . The autonomous driving device according to  claim 10 , wherein
 the position of the vehicle on the map is recognized based on map information stored in a map database and a detection result of an external sensor mounted on the vehicle, the external sensor being configured to detect a surrounding situation of the vehicle   
     
     
         13 . The autonomous driving device according to  claim 1 , wherein
 the arrival determination unit is configured to determine that the vehicle has arrived at the destination when the vehicle remains stationary at the destination continuously for a predetermined arrival determination time or longer after the vehicle arrives at the destination.   
     
     
         14 . The autonomous driving device according to  claim 1 , further comprising
 a thing-left-behind detection unit configured to detect whether there is a thing left behind in the vehicle by comparing a state of the vehicle before the occupant gets in the vehicle and a state of the vehicle after the occupant gets out of the vehicle,   wherein   the notification unit is configured to send a notification to the outside of the vehicle when the getting in-out detection unit detects that the occupant has gotten out of the vehicle and when the thing-left-behind detection unit detects that there is a thing left behind.   
     
     
         15 . The autonomous driving device according to  claim 14 , wherein
 the notification is sent to a reception device external to the vehicle.   
     
     
         16 . The autonomous driving device according to  claim 15 , wherein
 the reception device is a mobile terminal of the occupant.   
     
     
         17 . A notification method which is performed in an autonomous driving device causing a vehicle to autonomously travel along a route to a destination in manned mode or unmanned mode comprising:
 determining whether the vehicle has arrived at the destination; and   sending, after determining that the vehicle has arrived at the destination in the determining whether the vehicle has arrived at the destination, a notification to an outside of the vehicle when getting in or getting out of the vehicle of an occupant is not detected within a predetermined getting in-out determination time.
